D The most aluminum was collected on Friday. n B

Category 1 400 According to the data, what are the best conditions for growing mold? A cold temperature and low humidity B warm temperature and high humidity C cold temperature and high humidity D warm temperature and low humidity n B

Category 1 500 What inference is supported by the information in the graph? A Only 10. 7 percent of all landfills have a permit to burn tires. B About one-third of all scrap tires are either exported or recycled. C Most scrap tires are illegally dumped to avoid tire disposal fees. D The supply of scrap tires is greater than the reuse of scrap tires. n D

Category 2 100 Apple cider containing yeast was placed in a sterile container and kept at room temperature. When small bubbles of gas formed in the cider 2 days later, a student asked, “What is producing the gas bubbles? ” Which statement is a hypothesis that could be tested experimentally to answer this question? A A container of cider without yeast should serve as a comparison. B Set up an apparatus to collect and test the gas. C Cellular respiration is being carried out by the yeast. D The rate of gas produced must be determined. n C

Category 2 200 The illustration shows volume levels of a liquid in a graduated cylinder before and after a sample was removed. According to this information, what was the volume of the sample to the nearest milliliter? n 9 ml

Category 2 300 The table shows four mass readings of one object as measured by four different balances. Which balance produced the most-consistent measurements? n T

Category 2 400 The dependent variable in this investigation is – A the gas released B constant light C the green plant n. A D water

Category 2 500 n C A student observes a garden plot. Several plants shaded by a tree are not as large as those of ht same species growing in the full sun. the student asks, “Why are the plants growing in the shade smaller than the plants growing in the sun? ” Which is the most reasonable hypothesis to explain the student’s observations? A The tree removes water from the soil. The drier soil limits the growth of those plants growing near the tree. B The tree removes minerals from the soil. The mineral-reduced soil limits the growth of those plants growing near the tree. C The tree blocks sunlight, lowering the light level in the shaded area. This limits the growth of this plants species which grows best in direct sunlight. D The tree blocks sunlight, lowering the air temperature of the shaded area. This limits the growth of this plants species which grows best at warmer temperatures.
